Having the HTML of a webpage, what would be the easiest strategy to get the text that’s visible on the correspondent page? I have thought of getting everything that’s between the <a>..</a> and <p>...</p> but that is not working that well.
Keep in mind as that this is for a school project, I am not allowed to use any kind of external library (the idea is to have to do the parsing myself). Also, this will be implemented as the HTML of the page is downloaded, that is, I can’t assume I already have the whole HTML page downloaded. It has to be showing up the extracted visible words as the HTML is being downloaded.
Also, it doesn’t have to work for ALL the cases, just to be satisfatory most of the times.
Literally all the text that is visible sounds like a big ask for a school project, as it would depend not only on the HTML itself, but also any in-page or external styling. One solution would be to simply strip the HTML tags from the input, though that wouldn’t strictly meet your requirements as you have stated them.
Assuming that near enough is good enough, you could make a first pass to strip out the content of entire elements which you know won’t be visible (such as
script,style), and a second pass to remove the remaining tags themselves.
